addr-spec

A wicked, fast UTF-8 email address parser and serializer. It provides

• unopinionated, correct parsing of email addresses (defined as addr-spec in RFC 5322),
• extremely fast serialization and deserialization using low-level memory management,
• UTF-8 support with NFC normalization as recommended in RFC 6532,
• format validation based on the grammar set out in Section 3.4.1, RFC 5322 and Section 3.2, RFC 6532,
• and extremely fast serialization and deserialization. (Did we mention it's really fast?)
